“…Furthermore, there are many interesting topics related to the topological effects of ring polymers: the probability of forming a local knot in a random polygon [ 111 , 112 ], flat knots (i.e., knotted ring polymers in two dimensions) [ 113 , 114 ], the mean square radius of gyration of ring polymers in melt [ 115 , 116 , 117 , 118 , 119 ], the minimal step number of a lattice knot [ 120 , 121 ], the relaxation dynamics of a knotted ring polymer in solution [ 122 ], etc. [ 123 , 124 ].…”
